Definitions
- the invention relates to a vehicle with a system for receiving voice commands.
- the US 4,856,072 A relates to a voice-activated vehicle security system, comprising: a first microphone which is suitable for being mounted within a vehicle and which responds to a voice instruction to generate an input signal; a second microphone adapted to be mounted externally of a vehicle and responsive to the voice instruction to generate the input signal; voice control means connected to the first and second microphones and responsive to the input signal to generate a voice instruction signal; memory means connected to the voice control means for generating a control signal in response to a match between the voice instruction signal and one of a plurality of stored voice recognition specifications; and loudspeaker means connected to the voice control means and responsive to an output signal to generate a voice message, the voice control means responsive to the control signal to generate the output signal.
- the US 2019/0248327 A1 further relates to an intelligent key adapted for use with a body control module (BCM) of an electronic control unit (ECU) for a vehicle, the BCM being configured to control electronic devices of the vehicle, the intelligent Key includes: A transceiver unit configured to communicate with the ECU; a control unit coupled to the transceiver unit; and a display unit coupled to the control unit; wherein the control unit is configured to connect to the ECU via communication between the transceiver unit and the ECU to control the operation of the BCM and to drive the display unit to display a state of at least one of the electronic devices controlled by the BCM.
- BCM body control module
- ECU electronice control unit
- the intelligent Key includes: A transceiver unit configured to communicate with the ECU; a control unit coupled to the transceiver unit; and a display unit coupled to the control unit; wherein the control unit is configured to connect to the ECU via communication between the transceiver unit and the ECU to control the operation of the BCM
- a first aspect of the invention relates to a vehicle with a system for receiving voice commands, having a first microphone unit in the interior of the vehicle and a second microphone unit on the outside of the vehicle, as well as an identification unit and a control unit, wherein the identification unit is designed to recognize whether an authorized person is in the area of the vehicle and if the presence of the authorized person is detected in the area of the vehicle, whether the authorized person is outside or in the interior of the vehicle, the control unit being designed to do so if the presence of the authorized person outside is detected of the vehicle to activate voice control by receiving voice commands using the second microphone unit, and when the person's presence in the interior of the vehicle is detected, in particular subsequently, to deactivate the voice control using the second microphone unit and voice control by receiving voice commands using the first microphone unit to activate.
- voice control is increasingly being used in modern vehicles. If a second microphone unit is arranged on the outside of the vehicle, a voice command can also be transmitted to the vehicle by people outside the interior of the vehicle.
- Such functions include, for example, opening a trunk lid, lighting functions, automatic driving control functions such as automatic and independent parking of the vehicle, temperature control, window opening, etc.;
- a first microphone unit and a second microphone unit are used.
- the respective microphone unit can include exactly one microphone or several microphones. If a microphone unit has more than one microphone, triangulation methods can advantageously be used to determine the position of the person speaking more easily. This can be used to determine whether the authorized person is inside the vehicle or outside the vehicle. In this case, the microphone units are part of the identification unit.
- An alternative solution is to determine the position of the authorized person through the identification unit itself, for example by means of electromagnetic waves when triangulation of the transmitter of a wireless key for the vehicle is used, for example a Bluetooth transmitter.
- the identification unit determines whether a person is authorized. Typically, an authorized person is assumed to be an authorized person if he or she carries a corresponding key or authorization code or triggers the transmission of it. The identification unit determines this and transmits the result to the control unit.
- the control unit further coordinates the signal detection from the first microphone unit or the second microphone unit and activates only the first microphone unit or the second microphone unit depending on the detected position of the authorized person (at least if microphone units are not used to determine the position of the person themselves), or only uses the corresponding signals of the approved respective microphone unit, for example those of the second microphone unit, when the presence of the authorized person outside the interior of the vehicle is detected.
- Activating voice control by receiving voice commands using the first microphone unit can therefore, on the one hand, mean activating the first microphone unit in the first place in order to have receivable and processable signals from the first microphone unit. On the other hand, it can also mean only using the signals from the always active first microphone unit. The same applies to the second microphone unit.
- the voice command of functions of the vehicle can be made significantly safer and more flexible, since certain functions of their execution can be excluded, while others can be permitted, and functions can be parameterized depending on whether the authorized person in command is inside the vehicle or outside the vehicle.
- the use of the system is particularly advantageous when current voice control is used, which can be activated with a predefined keyword or the push of a button.
- the system according to the invention advantageously ensures that there are no unauthorized voice commands using a microphone unit outside the vehicle comes, which are implemented in corresponding assigned functions.
- the authorized persons prefferably define at least one further third zone in order to carry out the voice control. Furthermore, separate functions are preferably carried out in this at least one further third zone, and preferably only in response to voice inputs that are made in this third zone.
- the vehicle further has a visual output unit, wherein the visual output unit is designed to generate a visual signal via the second microphone unit when the voice control is activated.
- the visual output unit preferably includes lighting system elements of the vehicle itself, for example the low beam, brake lights, or direction change indicators.
- the parking lights can be activated when the voice control is activated using the second microphone unit.
- the identification unit is designed to use at least one of the following to check the authorization of the person: physical key, wireless authentication unit, biometric identification.
- the means of authorization corresponds to the means that allows a person to unlock the vehicle and put it into operation.
- control unit is designed to activate the voice control by receiving voice commands using the first microphone unit only when all recognized authorized persons are in the interior of the vehicle.
- control unit is designed to deactivate the voice control by means of the first microphone unit and voice control by receiving voice commands by means of the second when the authorized person is detected outside the vehicle following a detected presence of the person in the interior of the vehicle Activate the microphone unit.
- system is used to receive voice commands and to execute functions of the vehicle assigned to the voice commands, the control unit being designed to execute a first subset of the functions only if the voice control is carried out by means of the second microphone unit and a The second subset of functions can only be carried out if the voice control has been carried out using the first microphone unit.
- a further functional restriction can occur by checking whether the vehicle is at a standstill.
- some of the functions can be restricted to only being operated when stationary, such as opening a trunk lid.
- control unit is designed to carry out voice control by receiving voice commands from any person present when the authorized person is detected.
- control unit is designed to carry out voice control by accepting voice commands only from the authorized person when the presence of the authorized person is detected.
- control unit is designed to leave a function activated by voice control outside the vehicle activated for a predetermined period of time when the presence of the authorized person in the interior of the vehicle is detected, following a detected presence of the authorized person outside the vehicle.
- control unit is designed to leave a function activated by voice control in the interior of the vehicle activated for a predetermined period of time when the presence of the authorized person outside the vehicle is detected, following a detected presence of the authorized person in the interior of the vehicle.
- control unit is designed to activate a function activated by voice control outside the vehicle when the authorized person is detected in the interior of the vehicle following a detected presence of the authorized person outside the vehicle activated for a specified period of time.
- the comfort for the authorized person can be increased, for example if ambient lighting through the vehicle's parking lights or low beam headlights in the dark ensures that the authorized person finds an illuminated environment after getting out .
- Fig. 1 A vehicle with a system for receiving voice commands according to an exemplary embodiment of the invention.
- Fig. 1 shows a vehicle 1 with a system for receiving voice commands.
- a first microphone unit 3 with two microphones is arranged in the interior of the vehicle 1.
- An identification unit 7 recognizes a person with a wireless vehicle key with a transmission range of fifteen meters, so that the presence of an authorized person in the vicinity of the vehicle 1 is recognized. Furthermore, the identification unit 7 recognizes that the person is outside the vehicle 1. This information is forwarded by the identification unit 7 to a control unit 9 of the vehicle 1. The control unit 9 then activates voice control by receiving voice commands using the second microphone unit 5. Voice commands that are received by the second microphone unit 5 allow a specific group of predetermined functions to be carried out on the vehicle 1.
- a visual output unit 11 is realized in that the direction change indicators of the vehicle 1 are activated and light up in orange for a period of two seconds.
- voice control is activated via the second microphone unit 5, this form of display is initiated.
- the identification unit 7 recognizes the If the person is present in the interior of the vehicle 1, the control unit 9 deactivates the voice control using the second microphone unit 5 and activates voice control by receiving voice commands using the first microphone unit 3. From now on, voice commands are possible in the interior of the vehicle 1, which allow the control and initiation of functions of the vehicle 1 that differ at least partially from the functions that can be activated from outside the interior of the vehicle 1.
- control of an air conditioning system can be commanded from the interior of the vehicle 1. From the point at which voice commands are possible in the interior of the vehicle 1, the processing of voice commands from people outside the vehicle 1 via the second microphone unit 5 is deactivated in order to prevent unauthorized execution of functions on the vehicle 1.
